How Does Body Mass Index Influence Outcomes in Patients After Lumbar Fusion?

Study Design: Retrospective study.

Objective: The purpose of the present study is to determine how body mass index (BMI) affects patient-reported outcome measurements (PROMs) after lumbar fusions.

Summary Of Background Data: Although greater preoperative BMI is known to increase the rates of adverse events after surgery, there is a paucity of literature assessing the influence of BMI on PROMs after lumbar fusion.
